What it does
Sast Semgrep is an agent skill from AgentSecOps/SecOpsAgentKit. Static application security testing (SAST) using Semgrep for vulnerability detection, security code review, and secure coding guidance with OWASP and CWE framework mapping. Use when: (1) Scanning code for security vulnerabilities across multiple languages, (2) Performing security code reviews with pattern-based detection, (3) Integrating SAST checks into CI/CD pipelines, (4) Providing remediation guidance with OWASP Top 10 and CWE mappings, (5) Creating custom security rules for organization-specific patterns…
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files and assets (for example `assets/ci_config_examples/github-actions.yml`, `assets/ci_config_examples/gitlab-ci.yml` and `assets/rule_template.yaml`).
It sits in Security, covering Static analysis and SAST. It works with Semgrep. The repository describes itself as: Security operations toolkit for AI coding agents. Give Claude Code 25+ skills to catch vulnerabilities, scan containers, detect secrets, and enforce policies automatically.
When your agent uses it
- Scanning code for security vulnerabilities across multiple languages
- Performing security code reviews with pattern-based detection
- Integrating SAST checks into CI/CD pipelines
- Providing remediation guidance with OWASP Top 10 and CWE mappings
Example prompts
- “/sast-semgrep”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify the primary languages in the codebase
- Run scripts/semgrep_scan.py with appropriate rulesets
- Parse findings and categorize by severity (CRITICAL, HIGH, MEDIUM, LOW)
- Map findings to OWASP Top 10 and CWE categories
- Generate prioritized remediation report
What it can do on your machine
Read from SKILL.md and the folder at commit 6e25a4b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
semgrepjq
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
semgrep.devowasp.orgcwe.mitre.orgsans.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sast Semgrep loads about 2.4k tokens when it runs, and up to ~9.7k if it reads all its reference files. Until then it costs about 146 tokens; SKILL.md has 825 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 825 words (~2,374 tokens).
“Perform comprehensive static application security testing using Semgrep, a fast, open-source static analysis tool. This skill provides automated vulnerability detection, security code review workflows, and remediation guidance mapped to OWASP Top 10 and CWE standards.”
